IMPROVED GRINDING-MILL.

'ro' ALL WHOM 1T MAY OONOERN:

Be it known that I, JOHN P. MOORE, of Morning View. in the county-oi` Kenton, amLState of' Kentucky, have 'invented a new und useful Improvement in Mills for Grinding Grain; and I do hereby declare that the following is aff'ull, clear, and exact description of the sume, reference being had to the annexeddrawings,

Figure 1 isaperspective' View.

Figure 2 is a. perspective view ofthe hopper.

' Figure 23 is a vertical section.

The sameletters in all the figuresare used to indicate identical parte. 'lhisi'nprove'rnent relates to the construction and arrangement of a mill for grindingl grain, using a. cylindrical runner and concave bed-stone.

In Vthey annexed drawings, A is the husk, and B is the hopper attnched to the case 13h-Which rests on the top of the'husk, coveringthe top of the runner und the shoe and spout.' The slide B2 is fixed by a set-screw, lin .such manner as may he desired to regulate the feed. G is the shoe, which is hinged to the casing of the bed-stone,` tandis-'agitated by means of nn arm, C1, resting upon a. knocke'r, D, set on -the shaft Of the runner. The spring C2, attached to the case, presses on top of the urm C1. rlhe runner E and bed-stone F are made or" French burr.` The runner is a'cylinder hung upon n. shaft, vthe journals Aof which run in boxes on the husk. The top of the euse enclosingthe bed-stone rests against a. set-screw, G, whiclrregulatesthe distance of the top of the bed-stone from the runner. The lower end of the case enclosing the bed-stone is suspendedby a. hook attached to the'rodH, which, resting on the bridge-tree H1, and being raised or depressed by the nut H2, is used for regulating the-.rels.,tion of the bed-stone to the runner, to vary the character of Work done, according to circiumstances.' The nut H2 rests on a spring-plate, I, the elasticity of which is sulicient to yield to any hard substance entering withl the grain, and which might otherwise injure the stone. K is the spout formed in the case to discharge the meal. l

What I cls'im as my invention,.'and desire to secure by Letters Patent, is

Supporting the. lower edge of 'the'bed-stone F by means of the screw-rod'H,nut H2, and springlI, arranged i as herein described, for the purpose offgiving elasticity to the bed-stone in its'relation to therunner.

" In tcstimonymvhereof, I have signed my name to this specification in the presence of 4two subscribing witnesses.
